05 prius new rear component speakers dont work

I am replacing the speakers on my 05 prius with premium JBL speakers

The replacements components speakers have their own passive crossover
the front installation went well i connected the speaker harness to the crossover which then feeds the woofer and tweeter. both front component speakers work fine.

HOWEVER
i installed the rear speakers in the same manner yet no signal
in troubleshooting i reconnected the old JBL woofer and still no sound!
Only after i reconnected the old JBL tweeter did the speakers function.
I did notice the rear jbl tweeters may have an inline crossover(filter) see pics the black tweeter is the front and the rear tweeter is white and has a transistor attached.

Q: what wires do i tap into to get a signal? it seems the signal is going through the tweeter first which then passes the signal to the woofer since the woofer goes silent if i disconnect the tweeter!
I appreciate any advice
Thanks!!!
